摘    要:目的 :研究青年下腰痛患者腰背肌耐力的变化。方法 :应用CYBEX - 6 0 0 0型等速测试训练系统和肌电图测试腰痛组 (n =4 0 )和正常组 (n =4 0 )的腰背肌耐力指标 ,进行两组间比较。结果 :腰痛组腰背肌耐力比与正常组无差异 (P >0 .0 5 ) ;腰痛组腰背肌肌电图波幅低于正常组 (P <0 .0 5 )、时程大于正常组 (P <0 .0 5 ) ,腰痛组腰背肌肌电图波幅随时间衰减程度大于正常组 (P <0 .0 5 )、时程随时间延长程度大于正常组 (P <0 .0 5 )。结论 :青年下腰痛患者存在着明显的腰背肌静态耐力下降 ,腰背肌耐力比与下腰痛关系并不密切。

Abstract:Objective:To ascertain the change of trunk extensors endurance in youthful patients with low back pain. Method: The index of trunk extensors endurance (ER?the amplitude and the duration of EMG) were measured in patients with low back pain(n=40) and healthy subjects(n=40) with CYBEX-6000 isokinetic testing system and Neuromatic 2000M/C electromyography instrument. All of the indexes were compared between the two groups. Result: There were no significant difference of ER extensors between the patients and healthy subjects( P >0.05). The amplitude of EMG of extensors in patients were lower than those of healthy subjects( P <0.05), the duration of EMG of extensors in patients were longer than those of healthy subjects( P <0.05), and the decrease of the amplitude of EMG of extensors in patients were greater than those of healthy subjects( P <0.05), prolonging of the duration of EMG of extensors in patients were greater than those of healthy subjects( P <0.05). Conclusion: In youthful patients with low back pain, trunk extensors static endurance significantly declined, but ER of trunk extensors seem not to be related to low back pain.
Keywords:chronic low back pain  Isokinetic testing  electromyography  trunk extensors  endurance
